I want to leave the score intact so I can sort by matching term frequency and then by score. I don't think I can do that if I modify all the similarity functions, but I think your solution would have worked otherwise.
It would be great if there was a way I could expose this information through a function query (similar to the new relevance functions in version 4.0). I'll have to see if I can figure out how those functions work. -Nick On Thu, Feb 16, 2012 at 6:58 PM, Li Li <fancye...@gmail.com> wrote: > you can fool the lucene scoring fuction. override each function such as idf > queryNorm lengthNorm and let them simply return 1.0f. > I don't lucene 4 will expose more details. but for 2.x/3.x, lucene can only > score by vector space model and the formula can't be replaced by users. > > On Fri, Feb 17, 2012 at 10:47 AM, Nicholas Clark <clark...@gmail.com> > wrote: > > > Hi, > > > > I'm looking for a way to sort results by the number of matching terms. > > Being able to sort by the coord() value or by the overlap value that gets > > passed into the coord() function would do the trick.
